New idea for gesture recognition implementation

I have just learned the State design pattern. It should simplify the gesture recognition process. Think further about the fact that adding multiple gestures will cause a lot of new classes. Create them inside a single file. Find out how to split code to the separate folders.

Start by reviewing the existing gesture-recognition implementation and identifying how gestures are currently represented. Evaluate whether the State pattern and a single file or separate folders best support adding multiple gestures. Done means the intended structure and implementation scope are agreed and documented.
